Forum Problems Installing LAMS: Re: problems after upgrating to lams 2.3.1

Inside the /etc/init.d/lams2 script it should look for JAVA_HOME - is your java in a non-standard place? Also if the script was installed by the unix installer then there would be a log file in /path/to/jboss/log/wrapper.log - there might be info there.

The variable java_home is ok but i think the script is wrong. First in function start the option -- $DAEMON_OPTS should be without space. But again it is not running. The variable $DAEMON_OPTS it is not set right(at least to me) it is

DAEMON_OPTS="$JAVA_OPTS \
-Djava.endorsed.dirs=$JBOSS_ENDORSED_DIRS \
-classpath $JBOSS_CLASSPATH \
org.jboss.Main $JBOSS_OPTS"
where JAVA_OPTS ="$JAVA_OPTS -Dprogram.name=$PROGNAME"
and $PROGNAME is not set. What should be the value of the variable?
Also in the start of the script is defined
JBOSS_OPTS=
So this again is null.
Could you please tell me the values?
Finally although i have installed lams with the unix installer there is no log file in /path/to/jboss/log/wrapper.log

The settings are fine - it's the same steps that the original run.sh does before running jboss. You're right $PROGNAME is missing, but it seems to work without it. JBOSS_OPTS are optional, so if it's empty, that's ok.
What you can do to debug is run your shell with 'bash -x' - and then execute the startup script from there. It might help pinpoint what the script is doing.

Hello Giannis,

Have you at any stage edited your run.sh?

I could be wrong, but for the wrapper to work, I think in run.sh you need to replace these lines (near the bottom):

$JAVA $JAVA_OPTS \
-Djava.endorsed.dirs=$JBOSS_ENDORSED_DIRS \
-classpath $JBOSS_CLASSPATH \
org.jboss.Main $@"

With these lines

echo "$JAVA $JAVA_OPTS \
-Djava.endorsed.dirs=$JBOSS_ENDORSED_DIRS \
-classpath $JBOSS_CLASSPATH \
org.jboss.Main $@"

Essentially printing the command instead of running it. backup your run.sh first then give this a try.

Jundir is this correct?

Luke

Thanks all very much for your responses.Yes Jun-Dir-Liew the settings are optional, i open the run.sh from jboss and the settings are the same.But i can't understand why it is not running form /etc/init.d/lams while it is running from run.sh.The message that i get when i check the status (sudo /etc/init.d/lams status) is
Removed stale pid file: /var/run/lams2.pid
LAMS 2 Server is not running.
Does anyone knows why i get this message?
I run the script with -x option and i check all the values of variables which are correct.So i guess that the syntax of the start-stop-command in the start function is wrong.When i echo it with the specific values that i have i get this

start-stop-daemon --start --background --make-pidfile --pidfile /var/run/lams2.pid --chuid lams:lams --exec /usr/lib/jvm/java-1.5.0-sun/bin/java -- -server -Xmx512m -XX:MaxPermSize=128m -XX:MaxNewSize=204m -XX:SurvivorRatio=32 -Dprogram.name=lams2 -Djava.endorsed.dirs=/usr/share/jboss-4.0.2/lib/endorsed -classpath /usr/share/jboss-4.0.2/bin/run.jar:/usr/lib/jvm/java-1.5.0-sun/lib/tools.jar org.jboss.Main start

Can someone check it or just post his script ?
As for the log file i will change it in a while(but i have never edited this).

Thanks again.

The init script used in our debian package can be found here:

http://lamscvs.melcoe.mq.edu.au/fisheye/browse/~raw,r=1.2/lams/debian_installer/lams2/debian/lams2.init

Just to clarify, you've installed the debian package, correct? In your first post you mentioned lams-unix-patch-2.3.1.tar.gz (separate).

Anyway, maybe a diff between your copy of the script and the above copy might help.

The link you gave me is not working.Could you please give another link?I have installed the unix package and not the debian package because when i first installed it the version for ubuntu didn't exist and so i continue with the version for unix.
Thanks again

Thanks

Hi sorry for the delayed response.Ok i checked the file and it is almost the same.I am thinking to unistall lams and install the ubuntu version.But as i can see there is not an uninstall script or anything else.What can i do in order to uninstall it properly?I think it is not a good idea just delete or just install the ubuntu version.
Thanks again for any response.

Hi Giannis,

Did you install LAMS using the debian package? if so, I think you can just run

# apt-get remove LAMS

And that will uninstall it for you.

Thanks,

Ernie

Hi Giannis,

If you remove the jboss directory that's pretty much it. You can also remove the database from mysql and also the content repository folders (see /etc/lams2 for location).

Also remove the lams2 script from /etc/init.d and I think that's all.

Thanks,

Ernie

Hello,just to clarify when you said "remove the jboss directory" you mean remove the directory lams.ear which is inside the tomcat dir and not the entirely tomcat dir,right?Because i also installed jboss with the unix package and i can't find how to unistall it too (If you know how to uninstall jboss please tell me,because i would like to install the deb pakcage).
Thanks.

To remove jboss, just delete the jboss folder. This is assuming you installed it by extracting it from a zip or .tar.gz from jboss.org.

When you install the lams2 deb package it will also install jboss4 as a debian package - so no need to keep your current jboss.
